The Mighty Sac in Queen's Attack [4 Knights Defence] gambit in TEAM

The following move order of Q's Attack 4N def:
1. h2-h3 .. b7-c7 .. g13-g12 .. m8-l8
2. Qg1-j4 .. Qa7-b7 .. Nj14-i12 .. Qn8-m8
3. Bi1-h2 .. Na10-c9 .. Qh14-e11 .. Nn5-l6
4. k2-k4 .. Na5-c6 .. Ne14-f12 .. Nn10-l9
5. Nj1-i3 .. Nc6-d8 .. d13-d11 .. Nl9-k7



Red here plays the natural 6.Nf3 and blue's gambits a pawn to activate bishop and the rook by playing d10 and at the same time attacking Q



Yellow accepts it and green usually does the same gambit with red rejecting it to go to Qe9 from where it can pressure blue's King. Not suspecting anything, blue develops his rook on Ra10 to also attack the queen


This is where The Mighty Sac comes with QxRa10!. After that R/Y team will be at least a rook up for the entire game, as I show what will happen after the sacrifice. Now best move that green can do is Nxk4, but red can simply remove the defender of the blue's rook that was captured - QxNc9!!



Blue now have a couple options - to take the red's Q, QxN, Ka7, but all of them are losing!
I'll show you a couple variations:

Game1:
1. h2-h3 .. b7-c7 .. g13-g12 .. m8-l8
2. Qg1-j4 .. Qa7-b7 .. Nj14-i12 .. Qn8-m8
3. Bi1-h2 .. Na10-c9 .. Qh14-e11 .. Nn5-l6
4. k2-k4 .. Na5-c6 .. Ne14-f12 .. Nn10-l9
5. Nj1-i3 .. Nc6-d8 .. d13-d11 .. Nl9-k7
6. Ne1-f3 .. b10-d10 .. Qe11xd10 .. m5-k5
7. Qj4-e9 .. Ra11-a10 .. Qd10xRa10 .. Nl6xk4

11. Nf3-e5 .. Ka8-b7 .. Qa9-b8+ .. Qf6xNe5

12. Bc7xQe5 .. Kb7-c6

Blue accepting Q, followed by a very strong e12 to thread checkmate, green comes out with Q to help green and sacrifice the queen to avoid checkmate. Completely winning for R/Y!

Game6:

Here blue avoids to take red's Q and instead captures his N on f3. B/G realizes that it doesn't work due to similar e12!!. The checkmate here is unavoidable again. Only thing green can do is to give up the knight with check, but after that, wherever blue's King goes he gets checkmated with the next move. here blue plays Ka7 followed by yellow's Ba9!!

Game7:
1. h2-h3 .. b7-c7 .. g13-g12 .. m8-l8

R/Y are much better in this variation despite red's position. You can take the sacrificed N by i-pawn too



There are a few more variations that can occur, but with all of them R/Y should be able to win!
